使用纯Javascript在HTML元素数组中查找元素

Question

After a click on my element i can display the path :

console.log(e.path)

This gave me an array :

[i.fi.fi-bubble, button.c-block, div, body.u-help, html, document, Window]

I want to find in this array if there is an element with class "c-block" with pure Javascript

Do you have any suggestion ?

Thanks

Use the below code:-

<script>
var array = ["i.fi.fi-bubble", "button.c-block", "div", "body.u-help", "html", "document", "Window"];
var index = array.filter(value => /c-block/.test(value));
console.log(index.length);
</script>
